Abstract

A display device (100) includes a cathode electrode (134a), a first anode electrode (130_1), a second anode electrode (130_2), a first light emitting layer (132_1) disposed between the cathode electrode (134a) and the first anode electrode (130_1), a first light conversion layer (170a) disposed above the first light emitting layer (132_1), a second light emitting layer (132_2) disposed between the cathode electrode (134a) and the second anode electrode (130_2), a second light conversion layer (170b) disposed above the second light emitting layer (132_2) and an auxiliary electrode (AE). The auxiliary electrode (AE) is electrically connected to the cathode electrode (134a), and a portion of the auxiliary electrode (AE) is between the first light conversion layer (170a) and the second light conversion layer (170b) in a top view direction (Z) of the display device (100).
